George Mason – Homestars Review

Cleaned up the mold in my attic
Had a mess of mold behind the insulation in my attic. Had a few small leaks, probably for years, and the insulation was disgusting when we took it down. It was soaked and full of mold. Nusite came in and did a complete overhaul of the attic, removing the basement. I though they were going to make a giant mess, but they were very professional and kept my house clean, despite a lot of traffic in and out for several days.

Joshua Persaud – Yellowpages Review

Fixed cracks in my basement wall
Had several cracks in my basement wall and they would leak whenever we had a heavy rain. It started about a year and a half ago and seems to have gotten worse over the past 6 months. I tried having my neighbor seal it, but it started leaking again within a few weeks. Called several waterproofing companies and got several quotes, some of them were outrageous (be sure to get several quotes). One gave a low price, but discovered they weren’t covered by wsib, not sure if they were insured at all.
Finally went with Nusite contractors for the job. They gave a reasonable quote and I liked the guy that came by for the estimate. They stayed within budget and cleaned up before they left. They said the job is under warranty and to call if any problems, but it’s been almost 3 months now and it seems to be working great.

Sarah Jack – Homestars Review

Sealed and waterproofed basement wall
After several years of chronic leaks, we decided to have our basement waterproofed once and for all. The team over at Nusite was professional, answered my questions during the project and stayed within their quoted price….which is always a concern for me when working with contractors. Great job overall

Julie Morgan – Homestars Review

Fixed several cracks in foundation
Last Spring, had a new central air system installed. The spot where they drilled through the foundation to run the hoses to the back of our house started to crack. Within 2 months, it left an 24″ vertical crack going right into the soil. Nusite was the third company to come out and gave a good price, and were located close by in Richmond HIll (in case we had problems later). They had to dig out a small part of our yard to get to the crack, but sealed it and didn’t leave a mess afterwards. They did the work on time and didn’t try to charge for anything above what they estimated. It’s been about 5 months now and has’t leaked yet, crossing my fingers!

Mark Lipton – Homestars Review

Waterproofed basement
Our basement leaked! Of course . . . we bought a 100 year old house! But my office needed to be in the basement permanently. I interviewed 10 different companies until we decided on the Steinbergs and their crew at Nu-Site! They are profession, reliable, courteous, honest, and they really make an effort to communicate with the client about every step of the process..

Rob Greenglass – Homestars Review

Waterproofed building during renovations
I am a contractor renovating a 120-year-old church, converting it to private residences. We had a moisture issue in the lower level. Geoff and his team at Nu-Site were extremely knowledgeable, and very professional in executing their contract. They quickly earned our confidence. We are very demanding of our trades. They easily rose to the task. We would use them again, and would recommend them in a heartbeat, both to other GC’s and Homeowners. Nick is a fantastic team leader.
